Sichuan Constructio (Group) Company P125 flat head tower crane and C5513 tower crane are involved in the construction of Guizhou Ren Chi expressway.

Ren-Chi Expressway is a 163.476 km long section of Renhuai-Chishui Expressway from Chishui to Wangmu in Guizhou Province. The Xi-Shui branch line is about 7 km long. It is located in Xishui County, Zunyi City, northern Guizhou Province. The P125 flat-headed tower crane and C5513 tower crane of Chuanjian (Group) Company participated in the construction of Guanzhai Da, which was built by No. The bridge and eighth tenders are handed over to the Tongzi river bridge built by the Luqiao Southern Co.

Sichuan construction tower crane participating in construction of Guizhou Ren Chi Expressway Project

Guan Zhai bridge is 998.08 meters long, with a maximum height of 102 meters. The P25 tower crane which participates in the construction of the bridge is a fixed attachment crane with a lifting height of 120m, a maximum lifting weight of 10t, a lifting weight of 1.5T at the end and a maximum operating range of 60m. The standard section adopts 2m cross section. It is a new type of flat-head tower crane designed and developed by Sichuan Construction Machinery (Group) Co., Ltd. It adopts LVF frequency conversion lifting mechanism. Series of variable frequency speed and amplitude control mechanism, RCV rotary amplitude control mechanism, the configuration of the mechanism are developed by the company for many years, with international advanced level of technical performance, smooth operation, simple structure, low failure rate, easy maintenance, safe and reliable.

The Tongzi River Bridge is 1131.6 meters long, with a height of 222.6 meters and a maximum height of 172 meters. The C5513 tower crane, which is designed and developed by Sichuan Construction Machinery (Group) Co., Ltd., is divided into two types: 8t and 6t. It has three types of cranes: track walking crane, fixed attachment crane and internal climbing crane. The C5513 tower crane used in this construction is a fixed and attached type of 6t machine. The lifting height is 130m, the maximum lifting weight is 6t, the end lifting weight is 1.3t, and the standard section is 1.6m.

With the rapid development of Expressway and railway passenger dedicated line construction in China, bridge engineering across rivers, deep valleys and gorges is becoming larger and larger, technical requirements are higher and higher, construction period is shorter and shorter. Because of its rich use form and good performance, Sichuan tower crane is widely used in national roads, bridges and water conservancy. And other key projects.
